Code formatting and line continuations with Javascript and CSS

I've had a question up on stackoverflow recently in an attempt to get a nice solution for adding a glyph with CSS to indicate a wrapped line (e.g. in a command line sample).

With a few good suggestions, I had a reasonable solution but it still required a bit of manual markup to prepare the example. Then I saw Pranav Prakash's post about syntaxhighlighter by Alex Gorbatchev.

With a few tweaks (see the stackoverflow question for the details), I'm now able to combine the best of both worlds: great formatting and syntax highlighting with syntaxhighlighter and also line continuation glyphs. Here's an example of the result:

public class HelloWorld {

public static void main (String[] args)

{

System.out.println("Hello World! But that's not all I have to say. This line is going to go on for a very long time and I'd like to see it wrapped in the display. Note that the line styling clearly indicates a continuation.");

}

}

NB: if you have javascript disabled, or reading this through a newsfeed (or if I hit a bug) you may not see the full effect. Here's a screenshot of what should be appearing above:

Now I just need to go back and update the code formatting in all my old posts. Basket!

There is a lot of competition in outsourcing software development, as there are many firms across the globe catering to clients looking for outsourcing their work. What is good is that the takers can choose the best from the lot. http://www.infysolutions.com.
